Now that GR supports this, I’m trying to get it to work with plots.jl, and so far I can’t figure out how. This is one version of the code I tried and it doesn’t work. Am I missing something obvious?

```julia
using Plots
plot(deg2rad.(pho.verticalangles), pho.candelavalues[6,:], proj = :polar, 
    theta_zero_location = "S", extra_kwargs = :subplot)

```

Transforming the input polar angles with `π/2 - θ` and using the `annotate!()` function, it is possible to get something like:
